Security arrangements were beefed up in Manipur on Sunday after some Imphal valley-based banned organisations called for a strike on Independence Day, officials said.
Security forces also conducted search operations in vulnerable areas of five districts and recovered arms and ammunition, the police said.
Preparations for the I-Day celebrations are in full swing across the state with BSF, police and Assam Refiles personnel and students joining rehearsals for march past to be held on August 15.
"Rehearsals for I-Day celebrations were held on Saturday at Peace Ground in Churachandpur district's Tuiboung area. Twenty-one parade contingents of BSF, police, students and Assam Rifles participated in the preparations," an official said.
Preparations are also underway in the capital Imphal with temporary gates being erected and hoardings being put up to celebrate Independence Day on August 15.
"Security measures have been significantly heightened after several militant outfits called for a strike on I-Day," another official said.
